Please check :
1. Debit and Credit of take on should be 0 (zero). If not zero they have missed some taken on entry.
2. In case of expense and cost center is given in file, compare Profit Center and Business in Cost center master and given in take over file.
3. Check for baseline date as SAP calculate due date on the basis of baseline date + payment terms.
4. Check acquisition years for asset accounting.
5. Take on accounts should not be have tick for Open Item Management.
