Hi Nitesh,
what exactly would you achieve:
1 AO Type and then different EH Types?
-> You can have a Condition Function in the EH TYpe in transaction /SAPTRX/TSC0TT (EM System)
2 Different AO Type per Purchase Order Type and then different EH Types?
-> Use relevant function on your AO Type in transaction /SAPTRX/ASC0AO (in your ECC system)
Best regards,
Steffen
