Hello Paul,
First of all I would like to say thank you for working your saprfc nodes.
Then, I had installed node-red-contrib-saprfc into my system. I could see the saprfc nodes after installing. But after restart they all disappeared. I reinstalled it but nothing changed.
You can see a screenshot about problem.
Do you have a reccommendation for this?

Thanks in advance

I was able to install the saprfc module successfully. Unfortunately, this error message always appears when starting Node-Red. Do you have any idea what it could be?

Hi,
I would like to pass "TABLES" parameters in call node.
Currently it seems only possible to pass "IMPORTING" parameters.
Thanks.

No where in your project Emonlib with ADS1115 support do you have the ability to contact or submit an Issue. I'm hoping by reaching out here that you enable the feature over there as I am having issues with the results. Running an esp32 w/ ads1115

Hi,

I tried to increase the number of RFC connections in line 93 in saprfc.js but it doesn't work. Is there another limiter somewhere?

After 4 parallel RFC connections, all other http requests have to wait until an RFC connection is finished.

This problem does not exist with Wildfly and JCo.

Hi Paul,

I have probably messed up some installation steps on the way, but I am not very experience in Linux and the fact that I am doing this in Suse makes it bit worse (I am using to Raspbian on a PI when it comes to Linux).

The server I am installing in x86 on Suse Linux, so I ran into issues installing node-rfc itself, but after cloning it I think I managed to install it after all.

Next I tried adding the your module from within the palette manager and it failed. I am seeing this at the end of the log file:

38 verbose stack Error: /root/snap/node-red/538/node_modules/node-rfc: Appears to be a git repo or submodule.

Did I install node-rfc in the wrong place? I don't really understand what these messages mean.

Hi,
While i try to call RFC, getting this error.
"Error: Pool configuration object must provide "connectionParameters";

Hi Paul,

I am finally up and running and I wanted to ask if you have some tips on setting up the filters for table read.
I am trying to filter on a date field in a table and this is what I pass and what I get back from SAP:

POSTING_DATE is a DATS 8 field and in SE16 I see the value as DD.MM.YYYY.
