Add-On cnvMat
If a material was created in SAP with a specific material type, it is difficult to change it afterwards. There is transaction MMAM which can be used to assign a new material type to a material. However, this is usually only possible if all stocks and open transactions have been cleared. Changes to the valuation class are only possible if the old and new valuation class are assigned the same balance sheet account. And - for many the most important limitation - multiple selection is not possible. Each material must be changed individually.
cnvMat is an add-on from conlutio, with which you can easily change the material type, even for many materials at the same time.
We would be happy to present the solution to you in detail in a web presentation.
Mass change the material type
With cnvMat you can change many materials in one run. The new material type and, if applicable, valuation class is automatically derived from a previously defined mapping.
Transaction MMAM is called in the background to convert each material. All consistency checks of the standard transaction are run through. A test run can also be performed. Problems that have occurred are then collected and can be evaluated grouped by error class. In this way, you can get a detailed overview of the problems to be expected in advance without actually having to change the data.
Change balance sheet account
In some constellations, the standard prevents the material type from being changed, for example if the new valuation class posts to a different stock account or if you want to switch between valuated and non-valuated material types. The conversion is then very time-consuming, documents have to be closed and stocks booked out.
If desired, individual checks that prevent the material type change can be bypassed. In the case of a different account, for example, our conversion tool automatically generates an accounting document in order to transfer the stock values from the old G/L account to the new G/L account. All processes are logged and can thus be traced transparently even during a business audit.
