I have noticed few cases recently where in I was unable to make changes in an implemented enhancement spots. For ex:
In program SAPLIQS0 --> Include LIQS0F40
ENHANCEMENT-POINT EHP603_INIT_SUBSCREEN_F40_01 SPOTS ES_SAPLIQS0.
Theres already an implementation created for this spot, however when I try to change it , SAP asks for access key..
Any idea on how can I make changes to these kind of enhancement spots?
