hi,

user defined modules or custom adapter modules can be used to do few thing which can't be done by standard SAP modules, typical example in file adapter would be:

Reading/ Writing excel file through file adapter

Generating PDF file through file adapter

Hi Mayank Gupta.

Hi,

You can also use Eclipse if you dont have NWDS. But I think you can't directly deploy it from Eclipse. You can use SDM for deployment.

Rather than using eclipse i would suggest you to download the NWDS as it includes the standard Eclipse features and SAP features :

For downloading

Varma,

We have used Custom modules for encryption and decryption purpose. There might be lot of other custom needs to, as specified by shabz above.

Raj.

[Shabarish_Nair]

there can be many situations. Some common ones are;

1. you want to perform a custom file validation on the incoming file and report it

2. you want to add an extra tag or message to the outgoing file

well the above are some samples... the decision is basically based on what your scenario demands and if it cannot be handled by the standard file adapter capabilities.

Hi Vijay.

Thanks for your response.

but what my doubt is cont we get the same things that you explained earlier with UDF(UserDefinedFunctions) in message mapping and also can you give me some examples on the above mentioned scenarios.

will be waitng for yourresponse.

regards.

Varma

[Shabarish_Nair]

its a choice of design.

for example, in case of validation, i can choose to either do it in the mapping or in a module. Now if i choose to avoid the mapping and directly do it in a module, i might be able to achieve a better performance since i can avoid the mapping stage and maybe bypass it as part of my design.

another example is the creation of excel or PDF files or reading excel or PDF files.

These are not a standard feature and hence will need a custom module. As somebody mentioned earlier, another requirement would be to do PGP encryption or Decryption, again not a standard feature
