Hi, experts.
I`m facing some situation below...
1. I got a error message "Internal error in FORM/FUNCTION get_prkexx(saplckmo) in position 10 with RC" when do GR for a material(mvt. type is 101).
2. This material has no goods movements this fiscal year.
3. So, I found some solution ---
a. It seems there are problems with material ledger
b. I need to confirm whether the material ledger is activated well or not
c. Delete standard price for that material in transaction CKR1
d. And do re-calculate standard price
e. And release it
I found solution like above, but I cannot do that because of my lack of CO experience.
So, my questions are here.
1. How to check material ledger is active or not?
2. When I do delete standard price for a material in transaction CKR1, there is a message "Deleting current standard cost estimates can cause inconsistencies" and no further action of it. How I can delete standard price of this material?
P.S) I have one production order of this material but I cannot GR for this material with error message "Internal error in FORM/FUNCTION get_prkexx(saplckmo) in position 10 with RC"
3. If I can do 2, how I can re-calculate standard-price of this material?
4. If I can do 3, how I can release of this standard-price?
I always appreciate you expert`s help.
Thank you.
