PS Does not snap shot Alternate Resource For Firmed Batches

On : 12.1.3.8 version, Anything not covered by other codes

ACTUAL BEHAVIOR
---------------
Find that the alternate resource is not present in Production Scheduling (PS) for firmed OPM Batches

EXPECTED BEHAVIOR
-----------------------
Expect to see the alternate resources present in PS

STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1- Define Alternate Resource for a certain Resource- Item
2- Create Firmed Batch on that Item
3- N/A
4- Run Data Collection
5- Run Production Scheduling Schedule (Without ASCP Plan Reference)

BUSINESS IMPACT
-----------------------
The issue has the following business impact:
Due to this issue, users cannot manually assign alternate resources in PS for OPM firmed batches


CAUSE

The alternate resource for batches that are Firmed at the header are not collected into ASCP and hence this data is not available to PS. This is the correct functionality as it is a positive user action to firm the batch header, without this action the alternate resource is collected into ASCP and is available in PS

SOLUTION

To implement the solution, please execute the following steps:

1. Go into the responsibility: Production Supervisor

2. Navigate to Batches

3. Do not set the batch header as firmed or create the batches from ASCP/PS and firm the resources without firming the header
