Want to know SAP MM Table, like table VBFA for SD Document Flow

Question

Hello Experts,
I want to know, direct relationship between GR against PO line item and IR against PO line item.
I want to know, is there any SAP table for MM which gives direct relationship between succeeding document and preceding document, similar to table VBFA for SD Document Flow.
We have EKBE table which gives information about GRs and IRs for PO Line items.
Consider following case,
We have PO with line item say P1.
Two GRs are done for the same item, say G1 and G2.
Also two IRs are done for the same item, say I1 and I2.
In table, EKBE it just shows that, G1 and G2 are done for P1.
Similarly I1 and I2 are done for P1.
I want the table showing that, I1 is done after G1 and I2 is done after G2.
(or may be showing that, I1 is done for G1 and G2)
Do we have such table in MM? If such table does not exist, is there any way to verify this case?
Please share your opinion.
Thanks in advance.

Amrut,
If it is a GR based IR (check PO item Invoice tab- GR Based IV checkbox), you will find this link in table RSEG. You will find the GR number & item number in Reference number & Reference number Item field (LFBNR & LFPOS).
If it is non-GR based IR, then I think only way is to get it through EKBE (which you have explained in your question) since these two are not linked directly.
