Dear OM Sharma,
Normally we use above mentioned programs
a) Generate new versions of the integration model (RIMODGEN)
b) Activate the newest versions (RIMODAC2)
We can automate if its going to be a routine variant that needs to be transferred from ECC to SCM but in your case its not advisable to automate dynamic variants. The integration models (IM) becomes inactive if there already existing variant for same material and plant already active on another IM.
We have Material Master IM in CFM1 to filter based on Plant, Material Type , MRP Type and more but not based on warehouse number so it needs to be enhanced within EWM not on the ECC IM as per my knowledge please inform if it makes sense and inform if you need more details.
Regards,
Sriram.
