Uploading image from iOS To SAP

[Former Member]

Hello,

I am trying to upload image from iOS to SAP(By using sap mobile platform 2.3) and having some problems.

I look into some discussions on this case before and still couldnt solve it.

What i am trying to do is :

send a photo from device to SAP and create that photo with abap into local machine

I have a rfc on SAP that receives string and when try to create a mbo from this rfc, string size automatically becomes 300 and i cant change it.

If i could receive the base64 encoded string to abap, i can create the image but because of the 300 length limitation that does not work for me.

Some people says use xstring on rfc but xstring seems to 1024 length and rawstring seems to be right choice in that matter but i couldnt create a photo from rawstring in ABAP.

I took the image into NSData then use base64 encoding into Another NSData and send this to SAP. but after this i tried to change the encoded rawstring into a form that can be used with 'gui_download' but i gives control_flush_error

I am new to SUP maybe i am doing it all wrong can someone plz explain to me how to do this. (And why i cant change string default size which is 300)

Thank you very much

Hello Ata,

I do not know if things changed a lot for MBOs in SMP 2.3, but in SUP 2.1.3 i have done it this way...

For MBOs and the size... Try by creating an Operation Based MBO of type OTHER, i have uploaded files (not images) to SAP via RFCs using XSTRING's, and STRING's. And separate them in sync groups.

If you are using XSTRING, The Operation Based MBO on the data source must have a BIGBINARY attribute, and the client parameter must be a BINARY(n) where n is your size input. In this case you must send a NSData to SAP, and do the encoding/decoding in SAP.

If you are using STRING, The Operation Based MBO is the same thing, but with a "No Size" String Attribute in the Data Source, and in the client parameter must be a String(n), where n is your size input. In this case you must send an Encoded String to SAP (base64 is one of the popular ones).

Do not try to change the encoding of NSData, the iOS encoding for NSData is fine, if you need to change the encoding/decoding try to do it directly in the file type or on SAP. If you are using iOS7 i believe that they have finally put a method for base64 encoding/decoding for NSData. If you are using an older iOS version try this method:

http://stackoverflow.com/questions/6006823/creating-a-base-64-string-from-nsdata

For information if the file has reached SAP or not, you can use the callback handler on the methods onReplySuccess and onReplyFailed.

Hope this information is useful, regards,

Thank you Daniel,

My problem is i cant create a no size string when i give a string import parameter rfc, MBO load argument attribute automatically becomes STRING(300) and i cant change it.(Even if i give STRING(400000) from client parameter it only takes 300 of them) What sap data type i should use in my rfc to get no size string ?

BTW i will try to send nsdata without doing encoding in iOS.

Hi Ata,

Can you reply with a print screen of your MBO?

We are using a plain STRING from SAP, no special handling or modifications...

*"  IMPORTING

*"     VALUE(PI_DOCID)                  TYPE  CGPL_EXTID    OPTIONAL

*"     VALUE(PI_NAME)                   TYPE  SKWF_URLP     OPTIONAL

*"     VALUE(PI_DESCRIPTION)      TYPE  SKWF_DESCR  OPTIONAL

*"     VALUE(PI_FILENAME)            TYPE  FPATTFILE       OPTIONAL

*"     VALUE(PI_LENFILE)               TYPE  SDOK_FSIZE    OPTIONAL

*"     VALUE(PI_STRING_LINE)       TYPE  STRING            OPTIONAL

*"     VALUE(PI_LINE_X)                 TYPE  XSTRING          OPTIONAL

*"  EXPORTING

*"     VALUE(PE_SUCCESS_CODE) TYPE  SYMSGNO

*"     VALUE(PE_SUCCESS_MSG) TYPE  CHAR0256

Is strange that the SMP 2.3 is forcing the size at the operation parameters, perhaps they are trying to force you to use XSTRING for uploads. You can try by creating a XSTRING field and go in that way.

If you still want to go with string, try to set a large size for your string in SAP.

(Remember, if the import is STRING type, you must send a STRING, not a NSDATA)

Hi Daniel,

Here are my screenshots, as you can see i just can't seem to change the string size. I will try to make this as you said with xstrings but i will prob need dynamic size strings for something else, so this is kinda big problem for me

Hello Ata,

I would like to be in touch because I'm starting with Xcode programing using SUP.

Please, send me a e-mail.
