Errors in Transaction SHMA - Binding has invalid value

Former Member — Thu, 29 Jul 2010 18:59:58 GMT

I'm trying to create a shared memory area in transaction SHMA

I entered the area name and the root class name and just kept all the default values. When I do a syntax check I get 2 major errors 1. Binding has invalid value, and 2. Synchronization has invalid value.

I don't see any settings for these attributes - has anybody seen this before?

Thanks,

Brent

Make sure that you created the class with option "shared memory enabled"

You must also create at least one instance attribute, otherwise I don't see what you will store in memory

Thanks Sandra. My class does have an attribute. It is a table of some fields from the material master that I'will need to access from another program. I was just thinking, do I have to generate an instance of the class before I do the syntax check? Is the syntax performed on the instance or the definition of the shared memory area?

Thanks,

Brent

I don't understand what you mean. The syntax check is only about abap code, so?

In fact, what class are you talking about? Is it the root class, or the generated class corresponding to the handling of the shared memory area (the one with the same name as the area)?

Here are tips to understand the relationships between the area and related ABAP classes:

Create area Z_MY_AREA via transaction SHMA, choose a ZCL_MY_DATA root class name (must either exist or it can be created manually within SHMA; it must have attribute "SHARED-MEMORY ENABLED")
You must define in this ZCL_MY_DATA class at least one instance attribute
When you save the area, SAP creates automatically a class with the same name as the area (Z_MY_AREA), which inherits CL_SHM_AREA (which itself inherits CL_ABAP_MEMORY_AREA), and with an attribute named "ROOT" type ref to ZCL_MY_DATA

I got it, I was following a tutorial that left out a piece or two. I had my objects right but I was incorrectly using my root class. I also was doing a detach_commit on the incorrect instance.

Thanks for your help you got me pointed in the right direction.
