BAPI_OBJCL_CHANGE for MARA Characteristic value not replaced

Hi,

I use the BAPI BAPI_OBJCL_CHANGE to update the value of my characteristic, it works very well if the value does not exist but if a value already exists the new value will be added to the old one while the characteristic is of type Single Value.

I don’t see what I’m doing wrong.

Example :

– Z_XXX: current value in BDD = ‘PP1’

I send a new value ‘PP9’, after calling the BAPI I have the following result:

– Z_XXX: values

​​- ‘PP1’

– ‘PP9’

I just want to have the value ‘PP9’.

Thanks for your help.
