Length of MARA-BISMT 'old material number'

Hi,

I'm working on an ERP implementation project and we are facing the following issue:

For reference, reporting and look-up purpose we would like to store the previous used material number from the legacy system in the field mara-bismt in the material master of SAP. Unfortunately we have thousands of legacy material numbers exceeding the field length of 18 characters defined for mara-bismt.

To shorten the original material number is not an option, also using the short text to keep this information is not suitable.

Does anyone of you face a similar situation? How, did you manage it?

Thanks for your help,

Frank

    dont use the BISMT field, create a material classification with old material number as characteristic.

    You can define the length of the characteristic yourself in CT04.

    Hi

    Other possibility is create a customer field and set it in a dynpro (see Note 44410 - Integrating cust.-specific fields in matl master). After you could create a search help for this field.

    I hope this helps you

    Hi,

    Generally old material number and industry standard description fields are used to store legacy material numbers, but then it is limited to 18 characters only.

    So, in order to increase the field lenght it is better to use characteristic field in the material classification as suggested by Jurgen.

    Many thanks to you all.

    There's one question left, if I will setup/use the classification, will there be an easy way to find a material by searching for a value maintained in the classification view?

    Thank you,

    Frank

    • there is a business function for long material numbers in a DIMP system

      see note 1597790 - Activation of Long Material Number in DIMP

      Yes you have to use CLFMAS to distribute the classification. CHRMAS for characteristics and CLSMAS for classes if you dont maintain them manually in the target system.
