Issues with P0911Z1 creating duplicate documents or batches

hi,

we are using P0911Z1 to place journals from an external system in the z table to F0911 for reviewing before posting.

for one user, this process is creating either of the 2 situations:

1. creates one batch with duplicate documents OR,

2. creates duplicate batches with one document

it should only create one batch with one document.

I have reviewed the R09110Z report produced and it is updating the F0911 with multiple transactions, where i think it should only have 1 transaction with mutiple records

given this is only happening to one user, i thought they may have inadvertantly changed the processing options. but reviewing their processing options and comparing to the Journal Entry Batch Upload Process
