Tables for Inter company transactions

Hi All,

Can you let us know in which table(s) we will get the link for the SD & MM document number for INTER COMPANY Transactions.

We are facing a big issue regarding this,sometimes system doesn't create the MM documents when the other company(code) has created the Sales documents and Vice Versa. i.e AR document created in one company and relevant AP document is not created in other company code.

We are looking for a table we can find out the link between the SO & PO or GI & GR or Sales Billing & MIRO documents or in any combination.

Our client has developed a "Z" which is of no use.

Do suggest.

Regards,
