When doing Item Availability Check in APO I need to use First date, what is the best approach?

[utsavar]

When I do an ATP check for a sales order item in ECC, the material availability date is sent to APO. My requirement is to send the first date of the line item in the sales order instead of the material availability date.

I used exit 'EXIT_SAPLATPC_001' to change column 'bdter' of table 't_atpcsx' to achieve my result. I have managed to get first date through Stack.

Though it worked, I am having issues with BOP, as it deletes the schedule line when I run it the first time in APO after ATP check. Surprisingly, if I run it a second time, it fixes the issue and gives expected results.

I suspect an issue in BOP tables, but am not able to pinpoint it.

I would appreciate it if you could give me any input. Thanks.

Hello Utsav,

why do want to use the Requested Date thru separate coding as a material available date ? This date is the date when the customer wants it which is being entered in ERP in VA01/02 into the Sales order position. Depending if this is the customer arrival date (incl. transportation) or as a goods issue date (if no transport time is applied in case of customer pickup at the warehouse) GATP will give you the resulting correct MatAvailDate automatically and will perform the respective Shipping- and Transportation scheduling already ... your case needs a bit more explanation "why" ?
