[Subcontracting] Bug 648937: Transfer WIP Item is lost when production orders are created from Planning Worksheet

[Chethan Thopaiah (ChethanT)]

Summary

• preserve Transfer WIP Item and transfer descriptions on Planning Routing Line
• propagate the values from routing lines through Planning Worksheet carry-out to production order routing lines
• cover both certified routing versions and base routings with integration tests

Testing

• Added tests to codeunit 139996 Subc. Planning Test
• Verified patch formatting and object ID uniqueness
• Build and test execution were not available in the current environment

Fixes AB#648937

What this PR does

This PR adds storage on Planning Routing Line for Transfer WIP Item and transfer descriptions, then copies those values from routing lines through Planning Worksheet carry-out into production order routing lines. The data flow matches the reported bug, and the selected BaseApp events fire at the right points: before the planning routing line is inserted and after the production order routing line has copied the planning routing values.

Problem-solution fit

Fit: Strong

The change directly addresses the missing planning-routing storage and propagation path. It covers both routing versions and base routings, which matches the two ways the affected value can be sourced.

Suggestions

S1 (🔴 High): Fix the failing base-routing test
The new base-routing test currently fails while carrying out the planning line because production order GU00000000 already exists. Fix the test setup or cleanup so the carry-out creates a unique firm planned order and the subcontracting test app is stable. The failure also makes later planning tests unstable in the same app.

Risk assessment and necessity

Risk: The product code is narrow, but it changes subcontracting planning-to-production data flow. If it is wrong, production orders created from Planning Worksheet can still miss WIP transfer behavior or carry wrong transfer descriptions. The current validation failure is the main remaining merge risk.

Necessity: The change is required so orders created from Planning Worksheet preserve Transfer WIP Item the same way direct production order refresh does. Without it, the transfer-WIP process can silently be skipped for planned subcontracting orders.
