How do i check BAPI has data after execution

[Former Member]

Hi All,

I am executing BAPI function. But it has no return structure. I do i check the BAPI has data or not after execution.

Please give me the solution ASAP.

Thanks

Hi Ravi,

You can check the node size to ensure that it has data or not.

for eg: If the node name is Sales, then wdContext.nodeSales.size() returns the number of rows.

Hope this helps you.

Hi Ravi,

You can check it with the help of size() method.

for ex: if u have the node name Z_Employee_Output which is created in the context to get the output of the BAPI.

Now u can use the follwing code, it will give the size of the return structure.

wdcontext.nodeZ_Employee_Output().size();

Hi Ravi

As mentioned by Maksim if u add input parameters to instance of (rfm)_Input and then execute the modelobject. the (rfm)_Output is child of this node.

And once u invalidate output, you can check for the size of the output.

As far as I know, all BAPI's have return structure, especially the ones which saves data in R/3.

Is this a custom remote function module or a BAPI ?

Nevertheless, if you are function module has a table (table can be both input and output),and you put values in the table as part of input, you may try this:

a) If there is a problem in execution of the function module, the Output structure - that particular node (table) in Web Dynpro will be empty.

However, this is not an ideal way but only a workaround(an that too not a good one).

Hi Karri,

If an RFM requires input parameters, these must be supplied to the instance of class _Input. Then the _Input.execute() method can be called.

Once the RFM has executed, and instance of _Output will be available as a child of _Input.

So every executable model class contains "Output" relation

which can be used to fetch result of BAPI call.
