VKM3

This tcode is used to release the credit block at sales order level. The most important difference between VKM1 and VKM3 is that VKM1 will show both sale order and delivery and you can block even the delivery if it is not PGId. On the other hand, VKM3 will list only sales orders.

In fact, both VKM3 and VKM1 use VKM4 programmatically to release the blocks. If you check with help of SE93, the program for VKM3 is RVKRED04 and VKM1 is RVKRED02.And the program associated with VKM4 is RVKRED01.If you check in the codes of both programs, you would see that there is usage of RVKRED01 in same, which is nothing but VKM4.The screen of VKM3 after execution looks like this.
