. NET connection to SAP system topic: C # (NO3) code for calling BAPI (7)

The above blog shows some structure and parameters of BAPI_USER_CREATE. Therefore, you need to call it in C # to clearly specify the parameters to be entered.

1. First reference the dll, and then start with the program: using SAP. Middleware. Connector;

2. The next step is to set the login parameters. Previous blog posts have described the following:

Public class MyBackendConfig: IDestinationConfiguration

{

Public RfcConfigParameters GetParameters (String destinationName)

{

If ("PRD_000". Equals (destinationName ))

{

RfcConfigParameters parms = new RfcConfigParameters ();

Parms. Add (RfcConfigParameters. AppServerHost, "192.168.1.3 ");

Parms. Add (RfcConfigParameters. SystemNumber, "00 ");

Parms. Add (RfcConfigParameters. User, "MENGXIN ");

Parms. Add (RfcConfigParameters. Password, "5239898 ");

Parms. Add (RfcConfigParameters. Client, "888 ");

Parms. Add (RfcConfigParameters. Language, "ZH ");

Parms. Add (RfcConfigParameters. PoolSize, "5 ");

Parms. Add (RfcConfigParameters. MaxPoolSize, "10 ");

Parms. Add (RfcConfigParameters. IdleTimeout, "60 ");

Return parms;

}

Else return null;

}

Public bool ChangeEventsSupported ()

{

Return false;

}

Public event RfcDestinationManager. ConfigurationChangeHandler ConfigurationChanged;

}

3. Set a method to reference the login parameter class:

Public void nco ()

{

IDestinationConfiguration ID = new MyBackendConfig ();

RfcDestinationManager. RegisterDestinationConfiguration (ID );

RfcDestination prd = RfcDestinationManager. GetDestination ("PRD_000 ");

RfcDestinationManager. UnregisterDestinationConfiguration (ID );

Nco (prd );

}

4. Then the call code is started. The following code is all released, and a line of description is displayed:

Public void nco (RfcDestination prd)

{

// Select the name of the BAPI to be called

RfcFunctionMetadata BAPI_COMPANYCODE_GETDETAIL_MD = prd. Repository. GetFunctionMetadata ("BAPI_USER_CREATE ");

// Create an "instance" that calls this BAPI"

IRfcFunction function = null;

Function = BAPI_COMPANYCODE_GETDETAIL_MD.CreateFunction ();

// Because the username is a field, you can directly assign it to the string.

Function. SetValue ("USERNAME", USERID. Text. Trim ());

// The next step is the password. Because the password is a structure with only one column, you can obtain the structure first.

Fcfcstructure PWD = function. GetStructure ("PASSWORD ");

// Set the content of this column in this structure

PWD. SetValue ("BAPIPWD", password. Text. Trim ());

// Pass the structure to the password parameter.

Function. SetValue ("PASSWORD", PWD );

// This is the login information and the type is also a structure, so the structure of this login information is obtained here

Fcirstructure logo = function. GetStructure ("LOGONDATA ");

// The following two values are the field values for setting the login structure.

Logos. SetValue ("GLTGV", "20110821 ");

Logos. SetValue ("GLTGB", "99991231 ");

// Upload the structure of the login information to LOGONDATA

Function. SetValue ("LOGONDATA", logo); // set parameters

// This is the address information, take the structure, assign a value, and then pass it in

Fcirstructure address = function. GetStructure ("ADDRESS ");

Address. SetValue ("FIRSTNAME", firstname. Text. Trim ());

Address. SetValue ("LASTNAME", lastname. Text. Trim ());

Address. SetValue ("DEPARTMENT", "Information Room ");

Function. SetValue ("ADDRESS", address); // sets the Parameter

// The following ults is the default account information, not required. We use it to set the language of the Logon account to ZH.

IRfcStructure DEFAULTS = function. GetStructure ("DEFAULTS ");

DEFAULTS. SetValue ("LANGU", "1"); // language code, corresponding to simplified Chinese

Function. SetValue ("DEFAULTS", DEFAULTS );

// The following is the RETURN, which is the structure of the RETURN result. Remember, here is different from above. above is Structure, and here is Table !!

IRfcTable returnStructure = function. GetTable ("RETURN ");

Function. Invoke (prd); // submit a call to BAPI

// The call result is displayed in the pop-up dialog box.

MessageBox. Show (returnStructure. GetString ("MESSAGE"). ToString ());

Prd = null;

}

5. The program running result is as follows:

6. log on to SAP, run SU01, input IT_XM01, and check the result:

Of course, if the user already exists and you still call this BAPI to generate the user, the system will be very interesting:

Use IT_XM01 to log on to the system. Everything is OK. The system status is as follows:

The newly created account has no permissions at all. You can call other bapis to add permissions to it !! The method is a bit different. You need to input a table as a parameter and release it in the next blog.
