[Former Member]

Hi Can you please let me know the procedure for converssion of non unicode to unicode?

Thanks in advance,

Hi

The Link will be helpful to you.

Very good document:

You need to use the transaction UCCHECK.

The report documentation is here

ABAP Unicode Scan Tool UCCHECK

You can use transaction UCCHECK to examine a Unicode program set for syntax errors without having to set the program attribute "Unicode checks active" for every individual program. From the list of Unicode syntax errors, you can go directly to the affected programs and remove the errors. It is also possible to automatically create transport requests and set the Unicode program attribute for a program set.

Some application-specific checks, which draw your attention to program points that are not Unicode-compatible, are also integrated.

Selection of Objects:

The program objects can be selected according to object name, object type, author (TADIR), package, and original system. For the Unicode syntax check, only object types for which an independent syntax check can be carried out are appropriate. The following object types are possibilities:

PROG Report

CLAS Class

FUGR Function groups

FUGX Function group (with customer include, customer area)

FUGS Function group (with customer include, SAP area)

LDBA Logical Database

CNTX Context

TYPE Type pool

INTF Interface

Only Examine Programs with Non-Activated Unicode Flag

By default, the system only displays program objects that have not yet set the Unicode attribute. If you want to use UCCHECK to process program objects that have already set the attribute, you can deactivate this option.

Only Objects with TADIR Entry

By default, the system only displays program objects with a TADIR entry. If you want to examine programs that don't have a TADIR entry, for example locally generated programs without a package, you can deactivate this option.

Exclude Packages $*

By default, the system does not display program objects that are in a local, non-transportable package. If you want to examine programs that are in such a package, you can deactivate this option.

Display Modified SAP Programs Also

By default, SAP programs are not checked in customer systems. If you also want to check SAP programs that were modified in a customer system (see transaction SE95), you can activate this option.

Maximum Number of Programs:

To avoid timeouts or unexpectedly long waiting times, the maximum number of program objects is preset to 50. If you want to examine more objects, you must increase the maximum number or run a SAMT scan (general program set processing). The latter also has the advantage that the data is stored persistently. Proceed as follows:

- Call transaction SAMT

- Create task with program RSUNISCAN_FINAL, subroutine SAMT_SEARCH

For further information refer to documentation for transaction SAMT.

Displaying Points that Cannot Be Analyzed Statically

If you choose this option, you get an overview of the program points, where a static check for Unicode syntax errors is not possible. This can be the case if, for example, parameters or field symbols are not typed or you are accessing a field or structure with variable length/offset. At these points the system only tests at runtime whether the code is sufficient for the stricter Unicode tests. If possible, you should assign types to the variables used, otherwise you must check runtime behavior after the Unicode attribute has been set.

To be able to differentiate between your own and foreign code (for example when using standard includes or generated includes), there is a selection option for the includes to be displayed. By default, the system excludes the standard includes of the view maintenance LSVIM* from the display, because they cause a large number of messages that are not relevant for the Unicode conversion. It is recommended that you also exclude the generated function group-specific includes of the view maintenance (usually L<function group name>F00 and L<function group name>I00) from the display.

Similarly to the process in the extended syntax check, you can hide the warning using the pseudo comment ("#EC *).

Applikation-Specific Checks

These checks indicate program points that represent a public interface but are not Unicode-compatible. Under Unicode, the corresponding interfaces change according to the referenced documentation and must be adapted appropriately.

View Maintenance

Parts of the view maintenance generated in older releases are not Unicode-compatible. The relevant parts can be regenerated with a service report.

UPLOAD/DOWNLOAD

The function modules UPLOAD, DOWNLOAD or WS_UPLOAD and WS_DOWNLOAD are obsolete and cannot run under Unicode. Refer to the documentation for these modules to find out which routines serve as replacements.

Hi Anji,

I want to convert the remote function module RFC_READ_TABLE from non unicode to unicode.

please can you tell me the procedure.

Please let me know whether i have to test this program using transaction in UNICHECK in non unicode first tor i have to test in unicode.

Please clear my doubts.

Thanks in advance.

Best regards,

As far as Standard programs or function groups are considered, U developers have no role to do any thing.

BASIS Team will have to upgrade the system for UNICODE COMPATIBILITY and that time shall apply all the patches.

u will have to think about Z prgms or fn grps only

please let me know if u need any more.

Thanks

Hi Kiran,

Thanks for your reply.

If we install uni code system whether this function module will work in unicode system.

if it is not working i i am planning to modify RFC_READ_TABLE to customer function module ZRFC_READ_TABLE and want to make changes according to that.

and one more thing function module support for reaidng data for small table. my requirement is thati have to modify that function module work for even larger table.

so please give me idea how i can proceeds.

Thanks in advance .

Hi

Table RODIR - gives you all FM which are obsolete based on release.

Please chek this. And if it is obsolete, u may have to modify as Z Fm as you said.

And I did not get the concept of small table & Huge Table.

Please tell in detail.

Thanks

Hi Kiran,

Thanks for your reply.

so my requirement is :

A problem occurs in function module RFC_READ_TABLE.

Reason and Prerequisites

The scope of function module RFC_READ_TABLE is very restricted. E.g., due to the fixed maximum row size only smaller tables can be accessed. There are several data types that cannot be handled, and also there are doubts regarding the Unicode compatibility of the function module.

so please give me clear idea of the table RODIR. As i tried to find the RFC_READ_TABLE in that i am not able to find . so please help me how to find this function module is obsolute or not.

Thanks in advance.
