GR/IR rounding difference in LC

Question

Hello Team,
We have client specific scenario in P2P cycle. Please find below our scenarios and suggest further on this issue.
We will Create PO                                                  QTY   Price    Amount.
                                                                                   10     100        1000
Then We book an Invoice                                          12     100        1200
Then we Goods Receipt                                            10     100        1000
Then we book a credit memo                                      2     100          200
After all above  transactions done, then, In MB5S -> we see a difference of 0,01 in the value of the GR and invoice,
even if the quantities are in balance:
                                                                                QTY   Price     Amount
                                                    Goods Receipt     10      100        1000
                                                    Invoioce receipt   10      100        1000.01
In FAGLL03 for the GR/IR account, we see also the open amount of 0,01
euro:
Thanks,
Raj.

This is probably because of rounding. I assume that . is decimal point in the example you have mentioned.
If you use distribution by percentage, it may not be possible to exactly split the quantity unless your percentages are nice round figures like 10% or 50%. So there will be some rounding off if you have 27%, 31%, etc.
The usual practice is to use the a smaller unit of measure if more accuracy is needed. For example, in your case, you may have used 3360 dm3 instead of 3.360 m3 (I know it does not sound logical since people are not used to dm3) or 3360000 cm3. This will make the splitting easier, but the downside is - there will be some confusion for the users - particularly vendor, goods recipient, etc.
