## Short answer

Plan the cleanup of failed IDocs: how many can be reprocessed in bulk after a root-cause fix, how many need hands-on work, and how long it takes.

**Help:** For example a missing customer, a closed posting period or an unmaintained mapping value that affects many IDocs.

#### Effort for the root-cause fix

**Key:** fix_hours

**Min:** 0

**Step:** 1

**Unit:** hours

#### Mass reprocessing speed

**Key:** mass_rate

**Type:** number

**Default:** 3000

**Help:** Throughput of BD87 or a scheduled reprocessing job after the fix.

#### Manual handling per remaining IDoc

**Key:** manual_min

**Type:** number

**Default:** 4

**Min:** 0.5

**Step:** 0.5

**Unit:** min

**Help:** Open, read the status message, fix data or edit the IDoc, reprocess, confirm.

**Min:** 0

**Step:** 10

**Unit:** IDocs/day

**Outputs:**

#### IDocs cleared by the bulk fix

**Key:** mass_count

**Expr:** backlog * fixable_pct / 100

**Format:** integer

#### IDocs needing manual work

**Key:** manual_count

**Expr:** backlog - mass_count

**Format:** integer

#### Bulk reprocessing time

**Key:** mass_hours

**Expr:** mass_count / mass_rate

**Format:** hours

#### Manual handling effort

**Key:** manual_hours

**Expr:** manual_count * manual_min / 60

**Format:** hours

#### Total effort

**Key:** total_hours

**Expr:** fix_hours + mass_hours + manual_hours

**Format:** hours

**Primary:** true

#### Calendar working days to clear

**Key:** elapsed_days

**Expr:** total_hours / (analysts * 8)

**Format:** days

#### Cleanup cost

**Key:** cost

**Expr:** total_hours * hourly_rate

**Format:** currency

**Primary:** true

#### Spare analyst hours per day after inflow

**Key:** spare_hours

**Expr:** analysts * 8 - new_errors_day * manual_min / 60

**Format:** hours

**Description:** Negative means new errors arrive faster than the team can clear them.

**Chart:**

#### Total effort (hours) vs share fixed by one root-cause fix

**Type:** line

**X:** fixable_pct

**From:** 0

**To:** 100

**Steps:** 20

**Series:**

- total_hours

**Disclaimer:** Planning model. Real effort depends on error mix, and some IDocs cannot be reprocessed without business decisions.

## Content

**Intro:** A backlog of IDocs in error is rarely hundreds of separate problems. It is usually a handful of causes repeated many times. This calculator shows why finding the dominant cause first is cheaper than working the list one IDoc at a time.

**Sections:**

#### How to use it

**Body:** Group your errors in WE02 or the IDoc monitoring report by status and by the status message text. Estimate the share that comes from one or two causes you can fix centrally, such as a missing master record, a locked period or a missing conversion entry. Enter how long that fix takes, how fast mass reprocessing runs in BD87, and how many minutes each remaining IDoc takes by hand. The tool returns total hours, calendar days and cost.

#### The method

**Body:** Effort is the root-cause fix plus bulk reprocessing time plus manual handling of the remainder. Calendar days divide total hours by analysts times eight. The spare capacity output compares daily team hours with the manual time needed for newly arriving errors, which tells you whether the backlog can shrink at all. If spare hours are negative, the team falls further behind every day regardless of the cleanup plan, and the real fix is preventing the errors at source.

#### Reading the chart

**Body:** The chart sweeps the share fixed by one root-cause fix from zero to 100 percent. The curve falls steeply because bulk reprocessing is far faster than manual handling. Moving from 30 to 70 percent often saves more hours than adding an analyst. Use it to argue for a short analysis step before the team starts reprocessing at random.

#### Common mistakes

**Body:** Reprocessing before fixing the cause just re-creates the error and adds status records. Another mistake is mass reprocessing during business hours into a posting routine that locks shared data. Finally, some inbound IDocs are duplicates of ones already corrected manually, so confirm with the sender before reprocessing old errors, especially for financial postings.

**Cta:** If the same errors return every month, Netray can help your team build an error-pattern report and approval-gated reprocessing assistant on top of your IDoc data.

**Faq:**

#### What is the difference between status 51 and 53?

**Answer:** Status 51 means an inbound IDoc failed to post in the application. Status 53 means it was posted successfully. Reprocessing moves a corrected 51 IDoc toward 53.

#### Where do I reprocess in bulk?

**Answer:** BD87 lets you select IDocs by status and message type and process them together. For large backlogs, schedule program RBDAPP01 for the relevant statuses in the background.

#### Should I delete IDocs I cannot fix?

**Answer:** Not without a decision from the business owner. Set an unfixable IDoc to a final status by agreed procedure so it leaves the error list but the audit trail stays intact.

#### How do I find the dominant cause?

**Answer:** Group IDocs by status message number and text in WE02 or an ALV report on EDIDS. The top two or three messages usually account for most of the volume.
