Problem in updation of register RG23A part 1 & 2

Hi,

We are following the returns process in the following way:

1) Create returns PO

2) GR against PO with movement type 161

3) Excise invoice using J1IS

4) Print out using J1IV

5) Credit memo using MIRO.

After posting the excise invoice when we are updating the register RG23A part 1, then in the "balance quantity stock" column, the quantities that we have returned are getting added to the stock & not subtracted. Kindly tell the solution to this.

We are also doing the returns process through 122 movement type for testing. In that after the RG23A part 2 register is geeting updated, the excise values are not subtracted from the registers for the returned quantity. Kinly also provide the solution to this.

Regards
