BAPIs not working

Hi  Friends

Am  facing two issues with my program ,

1) Two  BAPIs as per suggestion by client only ,am using in program  first  BAPI is   (   BAPI_MATERIAL_SAVEDATA )  is uploading table  MARD  but for  the field   PSTAT ( Maintenance status ) Its uploading only one letter

example if value is  DE  then Bapi is uploading only 'D

2)  second BAPI for create BATCH  (  BAPI_BATCH_CREATE )  is  not uploading  data in table  MCHB  its  giving below error

   'No Batches are possible for material  XXXXXXX  in plant  XXXX '         am not sure if its data issue or  bapi is now working

If any one of you have any idea then please let me know

Thanks
