Bug 550732: Keep routing descriptions when vendor changes

[Chethan Thopaiah (ChethanT)]

Summary

• preserve subcontracting requisition Description and Description 2 from the matching production order routing line when the vendor changes
• retain the existing work-center fallback when the routing line is missing, belongs to another work center, or has a blank Description 2
• apply the same fix to the IT BaseApp layer

Root Cause

Vendor validation refreshed requisition descriptions from the subcontracting work center instead of the production order routing operation.

Test

Added \ChangingVendorKeepsProdOrderRoutingLineDescriptions\ ([SCENARIO 550732]) in codeunit 139989.

Validation:

• Subcontracting app compile: passed, 0 warnings/errors
• Subcontracting test app compile: passed, 0 warnings/errors
• app/test publish: passed
• regression test against the currently published unmodified Base Application: failed as expected, proving the old behavior
• final execution with the updated Base Application is blocked locally by the existing Base Application compiler/platform AL0126 mismatch; CI should run the integrated validation

Fixes AB#550732

$\textbf{🟡\ Medium\ Severity\ —\ Testing}$

The new test ChangingVendorKeepsProdOrderRoutingLineDescriptions only covers the branch where the production order routing line is found and its own Description/Description 2 are reused. It does not exercise the new fallback branch (added identically in both the W1 and IT layer tableextensions) that restores the Work Center's Name/Name 2 when ProdOrderRoutingLine.Get(...) returns false or the routing line's "Work Center No." no longer matches the requisition line's "Work Center No.". A regression in that fallback path (e.g. accidentally always taking the routing-line branch, or an inverted condition) could ship without any test failing. Add a negative test that forces RoutingLineFound = false (or a work-center mismatch) and asserts the requisition line falls back to the work-center descriptions.
