hi gurus ,

when creating material master for material type "fert"

I am getting the following error pl resolve urgently

*Enter a valid lot size (materials planning)*

*Message no. M3497*

*Diagnosis*

*The lot size specified in materials planning does not make sense here since quantity updating is not defined for the current material type in the plant specified.*

*Procedure*

*Choose a lot size for which the lot-sizing procedure "lot-for-lot order quantity" is defined.*

but I have maintained mrp type as PD and lot size as TB,the above error is received for this if I maintain EX system is accepting , but the earlier combination already exists for diff plants which are on live , pl come back at the earliest

thanks Regards

Hi ,

The system is working if we follw the instructions as you said..But what is the logic behind this enabling and disabling that tick mark in "Qty updating" ???

Dear,

If qty updaste tick is there, then only the stock is updated in teh system. In your case may be by mistake this tick is removed, hence system is looking for the same.
