Upload picture to maintenance order

Hello experts,

I am developing a WD application to create and modify PM maintenance orders, as a requeirement I need to upload a picture and attach it to the order, the functional team has showed me that in ECC you can do that easily. But I can't figure it out yet how to do that from WebDynpro, any comments or guidance will be welcome. So far I know how to uploead a file to the AS (Java Stack) but in this case the picture has to be in the ECC server and the PM order has to have that picture attached to it.

I hope you guys can help me out.

Thanks in advance,

JV
