Add a new list check of type PRC by selecting the new ALTE_IDE procedure from the LOV in the List Check field on the B.10.01 Verifications screen. If needed, double-click in the Where Condition field, and create a Where condition to be used for the check.
Now, open the B.20.01 Edit BOM screen, select a BOM node, and open the Single Position view. Select a position with piping material. Ensure that the ALTERN_IDENT position attribute is available. Click the button to open the B.20.01.41 Start Verification Job screen. Create a list job, select a list status from the LOV, and select the Best Qty option in the Issue Status Selection section. In the List Job Checks section, select the new ALTE_IDE from the LOV in the List Check field. Save and click Start to run the verification job.
Close B.20.01.44 to return to the Single Position view. Re-query the data to refresh the screen. The Value field of the ALTERN_IDENT attribute shows the appropriate ident codes, separated by semi-colons.
