Wrong G/L account is determined for security deposit - Move in through CRM

Hi Experts,

We are facing an issue where security deposit is posted to wrong G/L. After analysis we found out that it is because of the MDT that we are using has AD ID defaulted to 01 for contract.

In CRM there is no Account determination ID field at Contract Account Level but there is Account detrmination Field at Contract level,During Move In process system is picking Account detrmination ID from Contract level to determine GL Account.

The reason for defaulting ADID to "01"  is because there are too many ADID's in our system and it wont be possible to create separate MDT for each one.

So what I want to know, is does anyone has come accross such scenario? When you create move in from CRM is there way to dynamically determine ADID that will be used by MDT.

Thanks,

Suhas.
