Copying Batch Characteristics Value from Standard SAP Table Field

Question

Dear Experts,
1. While creating a user-defined Batch Characteristics 'CREATED_BY' using ct04,  on the Additional Data tab, I filled  the following fields as follows:  Table Name = MCHA,  Field Name =ERNAM.
'CREATED_BY' was then assigned to a batch Class TRIMMED (of class type 022).
TRIMMED  was assigned to a batch managed material ADE245DD.     
After posting co15 (confirmation of production order) for material ADE245DD, the value in table MCHA & field ERNAM is automatically copied into the Batch Characteristics value field of u2018CREATED_BYu2019  for the generated batch.
2. But I am unable to achieve the same result when I create another Batch Characteristic with similar settings in the Additional Data tab as follows: Table Name = MARC, Field Name = DISPO.
After doing co15, the value stored in table MARC and field DISPO does not get copied into the Batch Characteristics value.
Please what do I need to do in Scenario 2 above to achieve the same result as in Scenario1?
Regards

Hi,
Table and field used in additional data table should be related to the object than only it will work, for e.g. MCHA and ERDAT will work if you create a characteristcis and assign it to class type Batch (022/023) because MCHA table has Batch no. as primary key,
this implies for using material specific table e.g. MARA , you should use characteristics with class type 001 (Material class) , try using with table MARC also
