ATP Scheduling based on Custom fields

Hi experts,

Requirement is that scheduling needs to be happen in APO side based on custom fields at the sales order header level. To achieve this, here are the steps i have followed:

1. Enhance the KOMGO and KOMGU structures in the APO side.

2. Written code in user exit: FV45VFZY_USEREXIT_CATALOG_VALU in ECC side to populate the field catalog with custom field name and related value.

Functional team has already configured the condition record based on the custom fields at the APO side. Whenever i'm performing the ATP check in ECC side, scheduling screen shows that condition record has been found and determined, but couldn't see the dates reflecting in the ECC side.

One weird part is forward scheduling happens sometime even though my requested delivery date is well in the future. I believe this requirement is common in most of the APO GATP area. Can you please let me know is the issue in the code or configuration and related steps to correct it.

    Hi ,

    Look at exits APOSC002.and APOSC001       for doing scheduling using custom field.

    from Requested delivery date  the material avl. date will be calculated and on required MAD materials are not avl. , then forward scheduling might happen , if supplies are in future.

    Hello Karthik,

    For transportation scheduling, after enhancing the new fields and if you had passed the relevant fields in the field catalogue to APO, it should work as expected. You can check the internal calculations in the following exit to see if everything is as expected. EXIT_/SAPAPO/SAPLVCRM_002. This is the exit that has been provided by SAP to perform any changes to the calculated scheduling results.

    Hope this helps.

    Pretty vague question.  There is more than one place where scheduling can take place within GATP, that can be affected by conditions and by enhancement of the field catalogue.

    Are you talking about transportation/shipment scheduling of the item schedule during GATP?   Or....?

    Best Regards,
