In this sample we are going to change a production order by using the function CLOI_CHANGES_UPL_31. This, for example, could be useful, if an external programm does the planning of the productions orders and sends back the changes to SAP.

To change the header data you need the production order number and the fieldname you are going to change. You can get an overview of the fields in the SAP documentation, which can be found here: here

In our sample we change the Start Date (Field GSTRP) und the End Date (Field GLTRP). You can also change the quantity (Field BDMNG) or the Start Time (Field GSUZP). For Rescheduling the production order you have to fill the field METHOD with the value “SCHEDULE”. The table CLOI_MESSAGE_LOG_EXP contains the message codes. When the changing was successful we get following message back:

The Messagecode C7 - 071 means “Operation has been scheduled”. You can find the message codes in the transaction SE91. To get the function running a connection object (Con) must be available.

    }
    else
  
    {
    rMessage = "No Messages found";
    } 
     return rMessage;
 }

In our second sample we change the item data. We want to change the Start Time and End Time, and the Start and End Dates of a given operation (we define the operation in the variable VORNR). In this case the value of the field METHOD is “DISPATCH”, which reschedules all the item data of the production order. More changeable fields you can find again in the SAP documentation
