hi,
the error is pretty clear - you are trying to import a function module that contains "/" in it's name and this is not a valid character.
while the issue is clear, there might be two possibilities I could see to help you solve your issue:
1. you need a substitute variable for " / " and it looks like NWDS expects " % ";
-- I understand your function module lies in a private namespace, but NWDS is complaining about it; - looking at the implementation code, using a % could do the trick.
2. use *MED_PS_MEWRFCREF* as Search parameter and manually select the entry.
reading the source code of com.sap.dictionary.services_2.0.0.140708094527.jar, the method in question looks like:
private static String internalGetABAPNameFromBackendName(String name) { int nameLength = name.length(); int readIndex; for(readIndex = 0; readIndex < nameLength && isDefaultChar(name.charAt(readIndex)); readIndex++); if(readIndex >= nameLength) return name; SAPStringBuffer newValue = new SAPStringBuffer(nameLength); if(readIndex > 0) newValue.append(name, 0, readIndex); while(readIndex < nameLength) { char theChar = name.charAt(readIndex++); if(isDefaultChar(theChar)) newValue.append(theChar); else if(theChar == '%') { String theSubStr = name.substring(readIndex, name.indexOf('%', readIndex)); readIndex += theSubStr.length() + 1; newValue.append((char)Integer.parseInt(theSubStr, 10)); } else { throw new IllegalArgumentException((new StringBuilder()).append("Invalid char ").append(theChar).append(" found in ").append(name).toString()); } } return newValue.toString(); }it seems you might be ending in line 24 of the above code; while I'm not positive your jar is exactly the same as the one I posted, it's worth a try.
Hope it helps,
D.
