Hi Experts, 

I have created a custom table that has two fields, No. Series and Posting No. Series. While I post this Document, I am able to update Posting No. Series in the header but I am unable to update it in Document No. of Item Journal Line. It is posting the Item Ledger Entry with the unposted Document No. 

I cannot use Item Journal Batch because for one Item Journal Batch and template there are 2 set of No. series and Posting No. Series.

Please can anybody tell me how can that be done? 

Thanks in advance.
