Vf01 not pulling invoice list date of customer master

[Former Member]

hi

We required help for below

1.Customer master we maitanined invocie list to have billing done only on Tuesday

2.When sales order is created,it autamatically adjusted the header billing date to Tuesday

3.When delivery is created,likp-fkdat billing date is changing to delivery creation date while saving in vl01n

and when we try to do goods issue it has the actual goods issue date and not as per the sales order billing date that was coming from customer master invoice list

4.and When invoice is doing using VF01 or batch job it is updating the invoice billing date as actual goods issue movement date

I cannot see anything wrong in config as invoice list calendar has correctly setup tuesday as working day

Any help on this would be much appreciated
